BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is directed to compounds that are useful in treating or preventing pain, septic shock, pancreatitis, edema, rhinitis, asthma, colitis, arthritis, hepatorenal syndrome, cancer, bacterial and viral infections, ulcerative colitis, and Alzheimer's Disease. More particularly, the present invention is directed to benzodiazepine derivatives that useful in treating pain.

2. Discussion of Relevant Art

Two types of bradykinin receptor are known: The B1 receptor and the B2 receptor. A number of reports indicate an important role for the B2 receptor in the pathophysiology of pain. [e.g. Hall, J. M., Morton, I. K. M. The pharmacology and immunopharmacology of kinin receptors. In: Farmer S G (Ed). The kinin system. London: Academic Press, 1997; 944]. Hence, compounds that are B2 antagonists are useful in the relief of pain, including chronic pain and acute pain, e.g., chronic inflammatory pain, neuropathic pain, back pain, migraine, cancer pain, visceral pain, arthritis pain and post-operative pain.

DETAILED DESCRIPTION OF THE INVENTION

Thus, the problem underlying the present invention was to develop new compounds that are novel kinin B2 antagonists.

Accordingly, in one aspect, the present invention provides compounds that are useful in treating pain.

Methods of Preparation

The compounds listed in Table 1 were prepared as single compounds in a combinatorial array. The Table 1, column 4 designation of “yes” indicates that the target mass of the designated compound was found in >50% abundance in the MS spectrum. Similarly, the designation of “tentative” indicates that that the target mass of the designated compound was found in 15-50% abundance in the MS spectrum. Likewise the designation “no” indicates that the target mass of the designated compound was found in <15% abundance in MS 'spectrum. It will be understood by those of ordinary skill in the art that a chemical reaction which fails to efficiently yield the desired product within the context of a combinatorial protocol may nonetheless efficiently yield the desired product when the reaction is performed in a single reaction or parallel reaction format, without undue experimentation on the part of the chemist. In this regard, several of the compounds which were not prepared efficiently in the combinatorial array, were subsequently prepared in separate syntheses as shown in the Examples.

The reaction sequence depicted in Scheme 1, infra, describes a process for preparing compounds of formula (I) wherein X is represented by formula (i) or (ii), comprising reacting a compound of general formula II

wherein Y is a protecting group such as CBZ or FMOC, with an alkyl or alkenyl halide, such as allyl bromide in the presence of a base such as cesium carbonate to give compounds of general formula III;

deprotecting the compounds of formula III under standard conditions and then acylated the deprotected products of formula IV with thiophosgene or phosgene to yield isothiocyanates or isocyanates of formula V, respectively:

and subsequently aminating the compounds of formula V combinatorially in a multiwell plate with a selection of different amines to yield compounds of formula I wherein X is represented by formula (i) or (ii) shown above.

The general protocol for the preparation of the combinatorial library is depicted in Scheme 1 and specific experimental details are provided in the Examples below.

b is 0, 1, or 2; R¹, R², R³, R⁴, and R⁵ are as defined above.

In addition, certain compounds of the present invention and certain intermediates used in the preparation of the compounds of the present invention may be prepared according to one or more of the following general procedures, wherein, unless specified otherwise, b, R¹, R², R³, R⁴ and R⁵ are defined as above.

As illustrated in the scheme above, to a stirred solution of (7-chloro-2,3-dihydro-2-oxo-5-phenyl-1H-1,4-benzodiazepin-3-yl)-, phenylmethyl ester-carbamic acid (10 mmol) in DMF (140 ml) was added cesium carbonate (3.72 g, 11.4 mmol) followed by methyl iodide (2.0 g, 14 mmol). The reaction mixture was stirred at room temperature for 5 hours then concentrated in vacuo. The residue was taken in EtOAc (200 ml) and washed with brine (2×30 ml). The organic phase was then dried over MgSO₄, filtered and concentrated in vacuo. The products were purified by flash chromatography using dichloromethane as the eluent. The products (8 mmol) were added with conc HBr (33% in acetic acid) (50 ml) and were stirred at room temperature for 3 hours. The reaction mixture was poured into ether (300 ml), the precipitate was collected, and then taken in dichloromethane (250 ml) and washed with 2N NaOH (2×50 ml). The organic phase was dried over MgSO4, filtered and concentrated in vacuo to provide the desired compound.

As illustrated in the scheme above, to a solution of 3-aminobenzodiazepines (3 mmol) in dichloroethane (20 ml) and saturated aqueous Na₂CO₃ (20 ml) was added dropwise thiophosgene (0.7 g, 6 mmol). The reaction mixture was stirred at room temperature for 3 hours. The organic phase was separated and the aqueous phase was extracted with dichloromethane (50 ml). The combined organic phases were dried over MgSO₄, filtered and concentrated in vacuo. The product was purified by flash chromatography (100% CH₂Cl₂) to yield a compound of formula V.

As illustrated in the scheme above, to a solution of 4-fluoro-2-methyl-1-nitro-benzene (0.155 g, 1 mmol) in a 1:1 mixture of ethanol and water (20 ml) was added morpholine (0.435 g, 5 mmol). The reaction mixture was heated at 90° C. for 16 h. The solvent was evaporated in vacuo, the residue was taken in dichloromethane (50 ml) and washed with brine (3×10 ml). The organic phase was dried over MgSO₄, filtered, and concentrated in vacuo. The product was taken up in ethanol (20 ml) and heated at reflux. A solution of tin chloride (2M, 2.5 ml) in conc. HCl was added dropwise and heated at reflux for another 30 minutes. The solvent was then evaporated in vacuo, and the residue was treated with a 2M solution of sodium hydroxide until the pH of the solution was >10. The mixture was extracted with dichloromethane (50 ml) and the organic phase was dried over MgSO₄, filtered, and concentrated in vacuo. The product (0.032 g, 0.2 mmol) ((ESI) (M+H)⁺=192) was taken up in dichloroethane (5 ml), and 7-chloro-5-(2-chlorophenyl)-1,3-dihydro-3-isothiocyanato-1-methyl-2H-1,4-benzodiazepin-2-one(0.075 g, 0.2 mmol) was added. The reaction mixture was heated at 70 C for 16 h. The solvent was evaporated in vacuo, and the residue was washed with ether (2×10 ml) to yield the desired compound.

As illustrated in the scheme above, N₂ gas was bubbled through both DME and water for at least 3 hours. A solution of the imidoyl chloride (1 equiv.) in DME (1.5 mL/mmol imidoyl chloride) was placed in a N₂purged flask. Na₂CO₃ (1 equiv.), PdCl₂(dppf) (0.05 equiv.), boronic acid (1 equiv.) and water (0.5 mL/mmol imidoyl chloride) were added sequentially, and the resulting mixture was heated at 100° C. until the imidoyl chloride was consumed (typically 16 h). The reaction was then cooled, diluted with CH₂Cl₂ and water, and the layers were separated. The aqueous phase was extracted with CH₂Cl₂ (3×), and the combined organic phases were dried over Na₂SO₄, filtered, and concentrated in vacuo. The crude product was purified by silica gel column chromatography to provide the desired compound.

As illustrated in the scheme above, boronic acid (1.15 equiv.), Pd₂(dba)₃ (0.015 equiv.), and dry KF (3.3 equiv.) were placed in an oven-dried, N₂ purged flask. A solution of the imidoyl chloride (1 equiv.) in dry THE (2 mL/mmol imidoyl chloride) was added followed by a solution of P(t-Bu)₃ (0.045 equiv., 10% solution in hexanes) in dry THF (1.6 mL/mmol imidoyl chloride). The resulting mixture was heated at reflux until the imidoyl chloride was consumed (typically 16 h). The reaction was then cooled, diluted with EtOAc, and filtered through a small pad of silica gel. The silica was washed well with EtOAc, and the combined organic phases were concentrated in vacuo. The product was purified by silica gel column chromatography to provide the desired compound.

As illustrated in the scheme above, a solution of the benzodiazepine compound (1 equiv.) in dry THF (4 mL/mmol benzodiazepine, or slightly more if solubility was low) was added to a mixture of KHMDS (1.05 equiv., 0.5 M in toluene) and dry THF (2 mL/mmol benzodiazepine) immersed in a −78° C. cooling bath. After stirring for 5 min., a solution of trisyl azide (2.5 equiv) in dry THF (4 mL/mmol benzodiazepine) was added to the reaction, and stirring was continued until all the starting benzodiazepine had been consumed (typically 10 min.). Glacial acetic acid (4.4 equiv) was then added, and the mixture was warmed to 30° C. for 2 h. Saturated NaHCO₃ was added, the layers were separated, and the aqueous phase was extracted with CH₂Cl₂ (4×). The combined organic phases were dried over Na₂SO₄, filtered, and concentrated in vacuo. The product was purified by silica gel column chromatography to provide the corresponding azide compound.

As illustrated in the scheme above, polymer supported triphenylphosphine (Argonaut Technologies, 5-10 equiv) was added to a solution of the azide (1 equiv.) in THF (10 mL/g polymer) and water (0.8 mL/g polymer). The resulting mixture was stirred at room temperature until all of the azide had been consumed (typically overnight). The polymer resin was then removed by filtration, and was washed well with CH₂Cl₂ and MeOH (3× each). The filtrate was concentrated in vacuo, and the residue was redissolved in CH₂Cl₂. Any remaining water was removed with the aid of a separatory funnel, and the organic phase was dried over Na₂SO₄, filtered, and concentrated in vacuo. The amine was purified using a “catch and release” strategy with MP-TsOH resin (Argonaut Technologies): The product was dissolved in CH₂Cl₂ (10 mL/mmol product), and MP-TsOH resin (2.3 equiv) was added. The mixture was stirred for 1 h, and the solvent was removed by filtration and discarded. The resin was rinsed with CH₂Cl₂ and MeOH (3× each), and the washings were discarded as well. The product was then released from the resin by washing with 2M NH₃ in MeOH and CH₂Cl₂ (3× each). Concentration of the filtrate in vacuo provided the corresponding amine compound.

Biological Evaluation I. B2 Bradykinin Binding Assay A. Human Bradykinin B2 (hB2) Receptor Expression and Membrane Preparation

The cloned human Bradykinin B2 (hB2) receptor in the pCIN vector was purchased from Receptor Biology. The hB2 receptor was stably transfected into HEK 293 S cells and a clonal cell line was generated. Cells were grown in T-flasks with DMEM culture media containing 10% FBS, 2 mM glutamine, 600 μg/ml neomycin and an antibiotic cocktail (100 IU penicillin, 100 μg/ml streptomycin, 0.25 μg/ml amphotericin B). Membranes, expressing the hB2 receptor, were prepared from this cell line according to this protocol: Cells are harvested at 1 to 1.2 million cells/ml, pelleted, and resuspended in ice-cold lysis buffer (50 mM Tris, pH 7.0, 2.5 mM EDTA, with PMSF added just prior to use to 0.5 mM from a 0.5 M stock in DMSO. After lysis on ice for 15 min, the cells are homogenized with a polytron for 10 sec. The suspension is spun at 1000 g for 10 min at 4° C. The supernatant is saved on ice and the pellets resuspended and spun as before. The supernatants from both spins are combined and spun at 46,000 g for 10-30 min. The pellets are resuspended in cold Tris buffer (50 mM Tris/Cl, pH 7.0) at a dilution of 0.2-1 ml per 40 million cells and spun again. The final pellets are resuspended in membrane buffer (50 mM Tris, 0.32 M sucrose, pH 7.0). Aliquots are frozen in dry ice/ethanol and stored at −70° C. until use. The protein concentrations are determined by a modified Lowry with SDS.

B. hB2 Receptor Binding

Membranes expressing the hB2 receptor are thawed at 37° C., passed 3 times through a 25-gauge blunt-end needle, diluted in the bradykinin binding buffer (50 mM Tris, 3 mM MgCl₂, and 1 mg/ml BSA, pH 7.4, 0.02 mg/ml Phenanthroline, 0.25 mg/ml Pefabloc) and 80 μL aliquots containing the appropriate amount of protein (final concentration of 0.25 μg/ml) are distributed in 96-well polystyrene plates (Treff Lab). The IC₅₀ of compounds are evaluated from 10-point dose-response curves, where the serial dilutions are done on a final volume of 150 μL, with 70 μL of ¹²⁵I-Desamino-TyrHOE140 (Kd=0.05) at 50,000 to 60,000 dpm per well (0.03-0.04 nM) in a final volume of 300 μl. The total and non-specific binding are determined in the absence and presence of 0.1 μM (150 μL) of Bradykinin respectively. The plates are vortexed and incubated for 60 minutes at room temperature, filtered through Unifilters-96 GF/B (Canberra Packard), which were presoaked in 0.1% polyethyleneimine, with a harvester using 3 ml of wash buffer (50 mM Tris, pH 7.0, 3 mM MgCl₂). The filters are dried for 1 hour at 55° C. The radioactivity (cpm) is counted in a TopCount (Canberra Packard) after adding 65 μl/well of MS-20 scintillation liquid (Canberra Packard). Compounds of the present invention have demonstrated hB2 receptor binding at concentrations less than 10 μM.

Based on the above assays, the dissociation constant (Ki) for a particular compound of the invention towards a particular receptor is determined using the following equation: Ki=IC ₅₀/(1+[rad]/Kd),

-   -   Wherein IC₅₀ is the concentration of the compound of the         invention at which 50% displacement has been observed;     -   [rad] is a standard or reference radioactive ligand         concentration at that moment; and     -   Kd is the dissociation constant of the radioactive ligand         towards the particular receptor.         II. GTP[γ]³⁵S Binding Experiments on Bradykinin (B2) Receptors         A. General Information

The procedures below describe how to perform and interpret GTP[γ]³⁵S binding experiments designed to determine the activity of new compounds on the human B2 receptor.

B. General Procedure of the Assay

Human Bradykinin-2 GTP[γ]³⁵S Binding

Human Bradykinin-2 membranes (hB2 293s) are thawed at 37° C., passed 3 times through a 25-gauge blunt-end needle and diluted in the GTPγS binding buffer for the assay (50 mM Hepes, pH 7.4; 200 mM NaCl; 1 mM EDTA; 5 mM MgCl₂. To this added freshly prepared 1 mM DTT, 0.5% BSA, 1 μM GDP. The EC50 and Emax of compounds are evaluated from 10-point dose-response curves done in 300 μl with the appropriate amount of membrane protein and 100,000-120,000 dpm of GTPγ³⁵S per well (0.11-0.14 nM). Bradykinin (1-9) is used as the standard agonist at hB2. The ranges of concentrations tested should include a maximal concentration of 0.1 μM bradykinin in order to establish the E_(max).

The plates are vortexed and incubated for 60 minutes at room temperature, filtered on GF/B Unifilters (presoaked in water) with the Packard harvester using 4 ml/well of wash buffer (50 mM Tris, 5 mM MgCl₂, 50 mM NaCl, pH 7.0), minimum. The filters are dried for 1 hour at 55° C. The radioactivity (cpm) is counted in a TopCount (Packard) after adding 65 μl/well of MS-20 scintillation liquid.

Antagonist reversal studies are done in a similar manner except that the compound dose-response curve's are performed in the presence of a constant concentration of agonist (approx. 80% bradykinin E_(max); ˜5 nM). A standard B2 Antagonist is used as the reference antagonist at hB2. The ranges of antagonist concentrations tested should include a maximal concentration of 3 μM of the standard B2 Antagonist in order to establish the maximal displacement (D_(max)).

C. Radioligand: Preparation of GTP[γ]³⁵S

GTP[γ]³⁵S is acquired from Perkin-Elmer (250 μCi/20 μl). It is diluted from with 10 mM DTT, 50 mM Tris, pH 7 (dilute in 2 ml, 1.0 mCI/20 μ). Sonicate the solution, filter through a 0.45 μm filter, and freeze aliquots at −70° C. For the experiment, use ˜0.3 nM dilution of this tracer in the GTP binding buffer.

D. Data Analysis

The EC₅₀ and E_(max) of compounds are evaluated from 10-point dose-response curves done in 300 μl with the appropriate amount of membrane protein and GTPγ³⁵S per well and are calculated in Activity base with ExcelFit. The basal and maximal stimulated binding are determined in the absence and presence of standard reference compounds, respectively.

The stimulation (Stim) in the presence of compounds is expressed as the percentage of D_(max) of the reference antagonist. Values of IC₅₀, Ki′ and D_(max) for ligands capable of competing for agonist stimulated binding are calculated in Activity Base. Mean±S.E.M. values of IC₅₀, Ki′ and % D_(max) are reported for ligands tested in at least three dose-response curves.
